Northern Dynasty Minerals is an exploration and development company focused on the Pebble project, a copper-molybdenum-gold-silver project located 200 miles southwest of Anchorage in the Bristol Bay region of Alaska, US.
Northern Dynasty says the site is “one of the greatest stores of mineral wealth ever discovered.”
It hosts a measured and indicated copper resource of 6.5 billion metric tons and an inferred copper resource of 4.5 billion metric tons. The Pebble property's measured and indicated resources for molybdenum, gold and silver total 1.26 million metric tons, 53.82 million ounces and 249.3 million ounces, respectively.
The project stalled in 2020 during the permitting phase following a US Environmental Protection Agency (EPA) veto that suggested the proposed mine would damage the Bristol Bay watershed.
Early in 2024, the Supreme Court declined to hear the matter on procedural grounds, sending it back to the federal district court and the federal circuit of appeals before the Supreme Court would hear it.
Northern Dynasty spent the rest of 2024 advancing its case in Alaska's state court. In March of that year, it announced the filing of actions to vacate the EPA’s veto.
In 2025, shares of Northern Dynasty began to surge following Trump’s March 20 executive order that called for expedited approvals for domestic mineral production and included copper as a strategically important mineral.
Since Trump became president, Northern Dynasty has been attempting to work with the EPA to vacate the veto on the project. On February 18, the company agreed to grant the EPA a requested 90 day extension to allow for review by the new leadership in the agency, and granted a further 30 day extension on May 14 and 20 day extension on June 12.
The most recent news came on July 4, when Northern Dynasty reported it was in negotiations with the EPA to explore a potential settlement and a decision was expected within the next two weeks.
Shares in Northern Dynasty reached a year-to-date high of C$3.14 on July 16.
Year-to-date gain: 133.15 percent
Market cap: C$715.56 million
Share price: C$4.29
Imperial Metals is a mine development and production company with operations in British Columbia, Canada.
It holds a 30 percent interest in the Red Chris mine in BC’s Golden Triangle, with the remainder owned by Newmont (TSX:NGT,NYSE:NEM,ASX:NEM). Imperial also fully owns the Mount Polley copper-gold mine, which reopened in June 2022, and the Huckleberry copper mine, which has been under care and maintenance since 2016.
On May 9, the company clarified that claims by third parties that an injunction was granted to halt construction at the tailings facilities of its Mount Polley operation were incorrect, and that normal operations of the mine and construction of the tailing facilities would continue. This clarification followed an application for an interim injunction by Xatśūll First Nation on May 8, challenging provincial approval for a 4 meter raise of the tailings storage facility embankment.
A June 30 update reported that the BC Supreme Court reserved judgement on the case after a four day hearing, with a decision expected August 6. The court permitted construction of the tailings storage raise to continue in the interim, and Imperial stated it will not deposit tailings reliant on the raise until the court makes its decision.

FAQs for investing in copper
Is copper a good investment in 2025?
Many experts have a positive long-term outlook for the red metal based on supply concerns and its growing role in the energy transition. Copper's price has climbed to new all time highs in 2025, bringing many stocks with it.
Investors who are interested in copper should make sure to perform their due diligence, as the volatility and unpredictability of markets and economies at the moment means that nothing is guaranteed.
What is copper used for?
Copper is used in many industries, from construction to electronics to medical equipment. In fact, in 2022, 32 percent of copper globally was used in equipment manufacturing and 26 percent in building construction.
Two other growing sectors for copper are the burgeoning electric vehicle and green energy industries. Electric vehicles require a significant amount of the red metal per vehicle.
Check out our article on the topic for more copper uses.
How to invest in copper?
Investors can get exposure to copper in a variety of ways. Holding physical copper is possible, but plenty of storage would be required to hold any significant value of the metal.
For investors looking to invest in the metal without physically holding it, there are a few options. Copper stocks such as those on the TSX, TSXV and ASX are worth looking at. Additionally, there are copper exchange-traded funds and the copper options and futures markets on the London Metal Exchange.
How to invest in a copper ETF?
Copper exchange-traded funds (ETFs) focused on mining companies can be a good way to diversify an investment portfolio, and they can be a more stable option compared to individual copper miners or explorers. There are multiple options available on the market, and they can usually be purchased in the same way one could purchase stocks through a broker or trading platform.
In May 2022, Horizons launched Canada’s first copper equities ETF, the Horizons Copper Producers Index ETF (TSX:COPP). This Canadian copper ETF is focused solely on pure-play and diversified copper-mining companies.
There are multiple ETFs available on the US ARCA exchange as well. The Global X Copper Miners ETF (ARCA:COPX) tracks the Solactive Global Copper Miners Index, which includes copper miners, as well as copper explorers and developers. The other option is the United States Copper Index Fund (ARCA:CPER), which gives investors exposure to copper futures contracts by tracking the SummerHaven Copper Index Total Return.
How is copper priced?
The copper price is tracked in two ways: COMEX copper and London Metal Exchange (LME) copper. The COMEX and LME are both options and futures metal exchanges, with the former being headquartered in New York and the latter in London. COMEX copper is priced by the pound, while LME copper is priced per metric ton.
How is copper processed?
Once copper is mined, the ore goes through multiple steps to reach a market-ready state. First, the ore is ground to roughly separate the rock from the copper, as copper typically only makes up 1 percent of the mined rock.
The resultant copper is then slurried with water and chemical reagents, after which air is used to float the copper to the top of the mixture. After the copper is removed from this, it is typically at 24 to 40 percent purity.
Lastly, the copper is refined at a refining plant or smelter using one of two methods, pyrometallurgy and hydrometallurgy. Pyrometallurgy is employed for copper ore that is sulfide rich, while hydrometallurgy is used when the ore is oxide rich. The Investing News Network's guide on copper refining goes into further detail about how those processes work. Once these processes are complete, the copper is concentrated to up to 99.99 percent purity.
Where is copper mined?
Copper is mined throughout the world, with significant production found on every continent besides Antarctica. Chile was the top producer in 2024, putting out 5.3 million metric tons of the metal. Other major top copper producers are the Democratic Republic of Congo with 3.3 million MT, Peru with 2.6 million MT, China with 1.8 million MT. Indonesia and the US were tied in 2024 1.1 million MT of copper.
